(A) Excessive strength surcharge.
(1) In the event a user discharges wastes to the sewage works in excess of the limitations as stated in § 52.061(B)(20), the user shall pay a surcharge based upon the excess strength of its wastes.
(2) The surcharge will be calculated by obtaining the normal sewer service; then from the analysis of the discharge determining the strength of the discharge waste; selecting the proper multiplier based on the strength of the discharge and then multiplying the normal sewer service by that figure.
(3) The costs of treatment for each parameter removed by the POTW shall be reviewed at the time of and in conjunction with the review of the user charge. Surcharge rates shall be revised where necessary to approximate current treatment costs. These rates shall be in effect until the next rate review.
(B) Method of billing surcharge.
(1) The excessive strength surcharge shall be based on the following formula, with the total applied to the monthly bill of effected users:
Actual Test Results - Current Limits = Amount Exceeding Limitation
Surcharge = (AEL) × 8.34 × (TMF) × (CP)
AEL = Amount Exceeding Limitation (mg/1)
TMF = Total Monthly Flow (MGD)
CP = Cost per Pound
(2) No reduction in sewage service charges fees or taxes shall be permitted because of the fact that certain wastes discharged to the sewage works contains less than the current limitations.
